The idea is for a default popular culture sub to replace tv, movies, art, books, (maybe music , though that sub is big and probably the most active so no real reson too), ect from the defult list. It would be a general purpose sub, kinda like whatever, but for popular culture to allow more selectivity (users who care about the topics subscribing to them specificly) and in the above mentioned subs. I think it will increase or atleast slow the decrease of quality of posts to the subs, if/when and influx of users come in. (I'm an advocate of fewer defaults and forcing users to susbcribe to others subs. I think this would support that.)
